Lab tests are useful as a first assessment of a stove performance but you really need to test a stove in the field to assess how it actually performs in real life. With a series of Uncontrolled Cooking Tests and a probe we can measure emissions during cooking tasks done by local cooks. We can measure CO2, CO, PM2.5, Black Carbon and Organic Carbon and derive emission factors (per kg of fuel) and emission rates (per minute of cooking). We can deliver studies compliant with the GS Black Carbon methodology.
